Summary: The diffusion-controlled growth of interdiffusion zone between CM247LC superalloy and platinum-containing nickel aluminide bond coat was investigated. The growth mechanism of the interdiffusion zone was explained, showing two different parts: one without precipitates and one with precipitates. The compositional distribution, phase growth, and growth kinetics were strongly influenced by Pt and Al content. However, the types of topologically close-packed phases were the same regardless of the bond coat composition. In-depth TEM analysis revealed the presence of mu, sigma, P, and R phases, with significant differences in the compositions of certain components.

Summary: This article provides a comprehensive overview of the history, production, and demand of zinc. It discusses the production quantity of primary and secondary zinc, along with an economic analysis of zinc prices. The article presents the various methods used to obtain zinc from ores and analyzes the global zinc market and its applications. Furthermore, it explores technologies for zinc recovery from scrap, particularly from galvanized steel, emphasizing the importance of recycling due to the high volatility in zinc prices and its limited natural resources.

Summary: Single-layer and multilayer alloy deposits were electroplated onto a mild steel substrate, consisting of Zn and Fe alloys with different compositions. The corrosion resistance of these deposits was evaluated using potentiodynamic polarization method, while their surface morphology, crystal structure, and Fe content were characterized using scanning electron microscopy, X-ray diffraction, colorimetry, and energy-dispersive X-ray spectroscopy, respectively. The microhardness of the coatings was measured using a Vickers indenter. It was found that the Zn-Fe multilayer coatings showed significantly improved corrosion resistance compared to the single-layer coating, making them crucial for the automotive industry and steel-based vehicle parts.

Summary: This research aims to develop electrodeposited Zn-Ni alloy coatings with controlled dissolution behaviors. The study found that the variations in Ni concentration affected the surface morphology and electrochemical properties of the coatings. The addition of Ni influenced the coating thickness and corrosion rate, and the Zn-Ni alloy coatings showed improved corrosion resistance compared to pure Zn coatings. These findings highlight the importance of controlling dissolution tendencies for enhancing the stability of Zn-Ni alloy coatings.

Summary: The influence of laser surface structuring on the formation and internal strength of electrodeposited ZnNi coatings on steel sheets was examined. Surface structuring using extended direct laser interference patterning (xDLIP) was found to enhance the cohesive strength in the ZnNi layer, leading to the formation of interlocked crystalline structures. This interlocked crystal structure increased the cohesive strength in the ZnNi layer, as verified by roller peel tests.

Summary: Ni-based composite coatings have excellent properties, including high thermal and electrical conductivity, hardness, corrosion resistance, wear resistance, and magnetic properties. The addition of carbonaceous materials and ceramic particles as reinforcements further enhances the mechanical, tribological, and electrochemical performance of the coatings. Processing parameters and the types of ceramic particles play important roles in determining the properties of the coatings.

Summary: The review reveals that sacrificial Zn-Ni electroplating coatings on high-strength steels can lead to hydrogen embrittlement, which can be mitigated through baking treatments to reduce hydrogen content and delay structural failures. Microstructural inhomogeneities and potential defects also affect the performance of the coatings, contributing to hydrogen diffusion and trapping, accelerating structural failures.

Summary: This study aims to improve the microstructure, morphology, mechanical and corrosion behavior of Zn-Ni layers electrodeposited on low alloy carbon steel by optimizing factors such as nickel concentration, electrolyte temperature and current density. The best deposits were obtained with 50% Ni at 40 degrees C and j = 3 A dm(-2), showing a pyramidal morphology and the coexistence of delta-phase (Ni3Zn22) and gamma-phase (Ni5Zn21) structures, which can effectively protect the low alloy carbon steel against corrosion.

Summary: The article analyzes the challenges of transferring the electroplating process to additive manufactured ABS components, with a focus on surface quality. The success of electroplating on plastic surfaces strongly depends on the nature of the plastic and the additive manufacturing parameters used. Pre-treatment with levelling and sealing the surface is identified as an important challenge towards the success and reproducibility of the electroplating process.
